The 51-year-old news anchor had a bone marrow transplant two weeks ago to treat her myelodysplastic syndrome, a disease where one’s bone marrow doesn’t make enough healthy blood cells. Roberts took to “GMA’s” website to tell fans she is recovering well from her surgery.

“Today is what I like to call ‘Thankful Thursday, aka Friday Eve,'” Roberts writes. “I have been in the hospital 25 days now. My bone marrow transplant took place exactly two weeks ago. The only numbers that matter are my blood counts and they are… GREAT!”

Roberts received a bone marrow transplant from her sister, Sally-Ann, and she says the new cells “feel right at home in my body.”

“My doctors and rock star nurses are very pleased with my progress and I could not be more thankful for the excellent care I am receiving,” she says. “I have had some extremely painful days and it’s still difficult for me to eat because of all the chemo.”

Roberts adds, “I am hopeful that I MAY be well enough to continue my recovery at home next week and my sisters plan to come back to NYC for that milestone in my journey. I truly FEEL and thank you for your love, prayers and good wishes. And I return it to you tenfold.”
